I III/IIAII quil -Green lOd mvmwon HILAIRE G. De GAST ATTORN I'IYFOUNTAIN BACKGROUND OF THE INVENTION This invention relates to amusementdevices and, more particularly, to a toy employing a fountain or thelike.

Toy or amusement devices employing the principle of the fountain havebeen suggested in the prior art. In the toy fountain shown, for example,in US. Pat. No. 2,785,785, a handoperated pump is employed for providingan upwardly projecting stream of liquid. It has also been suggested, inthe toy shown in US. Reissue Pat. No. 23,612, that the flow of a liquidfrom an upper compartment into a lower compartment displaces air fromthe lower compartment through a vent pipe to operate a paddle wheelwithin the upper compartment. This device does not require a pump forits operation, being inverted to return the liquid to the uppercompartment.

SUMMARY OF THE INVENTION It is a principal object of the invention toprovide an improved fountain toy.

More specifically, it is an object of the invention to provide afountain toy having a closed fluid system and providing an upwardlystreaming liquid jet without employing external power means to operate apump.

A related object is the provision of a fountain toy of this characterwhich is reset by inverting the fluid system and which is caused tooperate by reinverting the system.

A further object of the invention is he provision of a plurality of suchfluid systems in a common fountain device.

Briefly, the invention contemplates the provision of a closed fluidsystem having a plurality of superposed compartments. A first tubeextends upwardly from the intermediate compart ment, having an open endnear the bottom wall of the intermediate compartment and a nozzle endwithin the upper compartment. A second tube extends downwardly from theupper compartment to the lower compartment having an open end near thebottom of the lower compartment. A third tube has an open end near thetop wall of the bottom compartment and an open end near the top wall ofthe intermediate compartment. The system is filled with a sufficientquantity ofliquid so that when the system is inverted the intermediatecompartment will be filled and the normally upper compartment will bepartially filled. Upon reinversion of the system to its normally uprightposition, the liquid will flow from the normally upper compartmentthrough the second tube into the lower compartment, displacing air fromthe lower compartment into the intermediate compartment through thethird tube, and displacing liquid from the intermediate compartmentthrough the first tube to cause a liquid jet toflow from the nozzle endinto the upper compartment. Various toy devices may be provided withinthe system to cooperate with or be operated by the liquid jet.

An embodiment of the invention includes an auxiliary compartment sealedfrom the fluid system and positioned between the intermediate and lowercompartments to increase the pressure head operating to provide theliquid jet. Another embodiment includes the concept of including twoindependent closed liquid systems with interspersed compartments, onesystem being inverted with respect to the other so that one system willoperate while the other system is being reset due to the inversionthereof. Yet another embodiment includes the concept of dividing theupper compartment into two chambers with siphon means for transferringliquid received from the liquid jet in the upper chamber to the lowerchamber from which it is transferred through the second tube to thelower compartment.

The foregoing and other objects, advantages, and features oftheinvention and the manner in which the same are accomplished will becomemore readily apparent upon consideration of the following detaileddescription of the invention when taken in conjunction with theaccompanying drawings, which illustrate preferred and exemplaryembodiments.

DETAILED DESCRIPTION Since the embddiment of FIG. 1 is the simplestversion of the invention and most clearly illustrates the operatingprinciples thereof, it will be described first. Referring to l FIG. 1,it will be seen that a fountain of the invention may comprise a closedfluid system 10 contained within a transparent plastic cylinder 12having an upper end wall 14 and a lower end wall 16. The fluid system isdivided into three compartments by transverse walls 18 and 20 which maybe made of the same transparent plastic material as cylinder 12 and endwalls 14 and 16. Dividing walls 18 and 20 are suitably sealed to theinner surface of cylinder 12 so that the only fluid flow between thethree compartments will be through tube means which will be describedpresently. Walls 18 and 20 form a first or intermediate compartment 22;walls 18 and 14 form a second or upper compartment 24; and walls 16 and20 form a third or lower compartment 26.

A transparent glass or plastic tube 28 has an open end 30 positionednear the bottom wall 20 of compartment 22 and extends upwardly throughcompartment 22 and wall 18, terminating a short distance above wall 18in a nozzle end 32. It has been found that tubing having an internaldiameter of approximately three-sixteenths of an inch is satisfactory.The nozzle end 32 is pinched or otherwise partly closed to provide asomewhat smaller opening.

Asecond transparent tube 34 has an open end 36 communicating withcompartment 24 at approximately the level of bottom wall 18 ofcompartment 24. Tube 34 extends downwardly through compartment 22 andwall 20 to a point closely adjacent to the lower wall 16 of compartment26. The lower end 38 of tube 34 is also open.

There is, in addition, a third transparent tube 40 having an open end 42within compartment 22 closely adjacent upper wall 18. Tube 40 extendsdownwardly through compartment 22 and wall 20 and has a lower open end44 at approximately the level of wall 20 communicating with compartment26. Tubes 34 and 40 preferably have the same internal diameter as tube28.

Closed fluid system 10 contains a liquid 46, which may be tinted anintense attractive color. As an example, a green liquid is employed inFIG. 1. The volume of liquid provided in closed fluid system 10 issufficient to substantially fill compartment 22 when thefluid system isinverted, as shown in FIG. 2, and partially fill compartment 24. It isto be understood that compartment 22 becomes filled through tube 40 withliquid flowing from compartment 26 and, when compartment 22 is filled tothe level of the upper end 30 of tube 28, the overflow will spillthrough tube 28 into compartment 24. After fluid system 10 is inverted,as shown in FIG. 2, for a time sufficient for the filling of compartment22 and partial filling of compartment 24, his then reinverted into theupright position shown in FIG. I. The liquid 46 within compartment 24will then flow downwardly through opening 36 and tube 34 intocompartment 26, causing compartment 26 to begin to fill with fluid 46.This will cause air within compartment 26 to be displaced upwardlythrough open end 44 of tube 40 and through tube 40 into compartment 22.This, in turn, will cause the liquid 46 within compartment 22 to bedisplaced upwardly through open end 30 of tube 28 and through tube 28and nozzle end 32 thereof. Due to the constricted opening 32 of tube 28the liquid flowing through tube 28 will project from nozzle end 32 as aliquid jet 48. The liquid from liquid jet 48 will collect along thebottom wall of compartment 24 and flow through open end 36 of tube 34and through tube 34 into lower compartment 26, further displacing airfrom this compartrnent to continue the operation until virtually all ofthe liquid in compartment 22 has been displaced. At this time, the jet4% will cease to flow, and the fluid system will be ready to be reset byinverting it as shown in FIG. 2.

The force of jet 48 is a function of the hydraulic head l-l createdwithin the system. This hydraulic head will be governed by theexpression H A-B, where A is the distance between the level 50 of theliquid 46 within compartment 24 and the level 52 of the liquid 45 withincompartment 26 and B is the distance between the top of nozzle end 32and the level 54 of the liquid 46 within compartment 22.

While the device may be used in the form shown in FIG. 1, it is to beunderstood that any number of toy devices may be incorporated therein tobe operated by the jet 48 and/or by the fluid flow within compartment26. Thus, for example, as illustrated in the embodiment of FIG. 4, a toyvolcano might be positioned within compartment 24 so that the liquid jet48 would appear as an eruption from the volcano. Alternatively, awaterwheel device could be incorporated within compartment 24' to beoperated by the jet flowing from nozzle end 32. As shown in FIG. 6, theliquid jet could be employed for revolving a jet spinner 56. The jetspinner would include a tube 58 connected with tube 28 and communicatingwith a revolving hub member 66 and through hub 60 to a plurality ofradiating jet pipes 62. As the fluid pressure operating in the systemcauses liquid to rise through tube 28 and tube 58, it is caused to flowrapidly through jet pipes 62 and appear as liquid jets extending fromthe open ends thereof. This will cause the hub to rotate with the resultthat a revolving jet spinner is provided. Other toys may be incorporatedfor operation by, or for use in conjunction with, the jet provided fromtube 28. Examples include a toy decorative fountain, a geyser, awaterfall, an oil well, a grist mill, a paddle wheel boat, a spoutingwhale, a fireman and hose, a fire boat, a stream beneath a bridge, aspring or grotto, and a coffee percolator. Other devices could beincorporated within the system to be actuated by the airflow as the airis displaced from one compartment to another.

The force of the jet may be increased by increasing the hydraulic head.This may be accomplished, as illustrated in the embodiment of FIG. 3, byincorporating an additional compartment between two of the compartmentsof the fluid system a. As shown in FiG. 3, an auxiliary compartment 64is positioned between compartments 22 and 26, being separated fromcompartment 22 by a transverse transparent plastic wall 66 and fromcompartment 26 by a transverse transparent plastic wall 68. Compartment64 is preferably completely sealed from compartments 22 and 26 and maybe filled with a second liquid 70 which is preferably of a contrastingcolor to liquid 46. For exampie, as shown in FIG. 3, liquid 70 is red,while liquid 46 is green.

While tube 28 will remain the same length as in the embodiment of FIG.I, the tube extending from compartment 24 to compartment 26 must beconsiderably longer. Thus, tube 34a extends from open end 36 incommunication with compartment 24 through compartment 22, wall 66,compartment 64 and wall 68 to open end 38 adjacent to lower wall 16within compartment 26. In like manner, a tube 40a has an open end 42adjacent top wall 18 of compartment 22 and extends down through wall 66,sealed compartment 64, and wall 68 to communicate through open end 44with compartment 26 adjacent wall 68. By virtue of this arrangement thedistance A is considerably larger than the distance A in the embodimentof FIG. 1. Since the hydraulic head H AB, is thus considerably larger inthe embodiment of FIG. 3, greater pressure will be available withincompartment 22 to provide a fluid jet 48 of considerably greater force.Various toy devices, as previously described, may be incorporated withinthe embodiment of FIG. 3.

It is also possible within the purview of the invention, to incorporatetwo or more closed fluid systems within a single device. In theembodiment shown in FIG. 4, for example, two fluid systems 10b and 100are combined within a single unitary device, one system being invertedwith respect to the other. As before, a transparent plastic cylinder 12encloses the device and has an end wall 14 at one end and an end wall 16at the other end. A first closed fluid system 10b includes threecompartments 22, 24, and 26, corresponding to similarly numberedcompartments shown in previously described embodiments. A transversewall 18 separates compartments 22 and 24. However, compartments 22 and26 are separated by one compartment 26 26c of three compartments formingclosed fluid system 100. System 10c also includes compartments 22c and24c. A transverse transparent plastic wall 72 separates compartments 22and 260; a transverse wall 74 is positioned between compartments 26c and26; a transverse wall 76 separates compartments 26 and 220; and atransverse wall 78 is positioned between compartments 22c and 24c.

Closed fluid system 10b resembles the closed fluid systems previouslydescribed. The first tube 28 extends from just above wall 72 ofcompartment 22 upwardly through wall 18 and terminates at a constrictednoule end 32 at a point within compartment 24. A second tube 34b has anupper open end 36b positioned within compartment 24 at a point below thelevel of nozzle end 32 of tube 28. It will be observed that, in thisembodiment, which incorporates a toy volcano, the tubes 28 and 34bextend upwardly through a volcano structure 80, both being positionedwithin a crater portion 82 thereof. When jet 48 projects from tube 28,it is received with in crater 82 and the fluid passes downwardly throughtube 34!). In the event that some of the fluid projects or splashes overthe edge of crater 82 and is received in the bottom of compartment 24, apassageway 84 is provided through the bottom of volcano and communicatesthrough an opening 86 to tube 34b. Thus, any excess fluid collecting atthe bottom of compartment 24 is also received in tube 34b and passeddownwardly therethrough.

Closed fluid system 10b also includes a third tube 401;, which has anopen end 42 closely adjacent wall 18 within the upper portion ofcompartment 22, and which extends downwardly through compartment 22,through wall 72, through compartment 260, and through wall 74, having anopen end 44 communicating with compartment 26. Fluid system 10b isprovided with a colored liquid 46 of one color (red liquid is employedas an example) of sufficient volume to fill compartment 22 and partiallyfill compartment 24 when the fluid system 10b is in its invertedposition (as shown in FIG. 4, this fluid system is shown in its uprightposition).

Fluid system is essentially the same as fluid 10b, being, however, ininverted position with respect thereto. Thus, as shown in FIG. 4, fluidsystem 10c is in its inverted position. A tube 28c has an open end 300closely adjacent to wall 76 within compartment 22c and extends throughcompartment 220 and wall 78 to terminate with a nozzle end 32c withincompartment 34c. It will be observed that, in the embodiment as shown inFIG. 4, nozzle end 320 is incorporated within a toy waterwheel deviceThus, nozzle opening 32c communicates with a water channel member 88which will channel water received from nozzle 320 to a position where itwill splash down (when fluid system 10c is in its upright position) upona waterwheel 90. While not shown in this figure, the waterwheel could beincorporated within a more elaborate toy representing, for example, agrist mill, or the like.

Fluid system 10c also includes a tube 340 having an open end 36ccommunicating with compartment 24c adjacent to wall 78. Tube 340 extendsthrough compartment 22c, through wall 76, through compartment 26, andthrough wall 74, terminating in an open end 380 closely adjacent wall 72within compartment 260. Fluid system 10c also includes a third tube 400having an open end 44c communicating at wall 74 with compartment 260.Tube 40c extends through compartment 26, wall 76, and terminates in anopen end 420 adjacent wall 7% within compartment 220.

A quantity of liquid 92 is provided within fluid system 100 ofsufiicient volume to substantially fill compartment 220 and partiallyfill compartment 240 when inverted as shown in FIG. 4. Compartment 220is filled from compartment 260 through tube 46c; an intermediate pointin the filling cycle is shown in FlG. 4. Liquid 92 may be of a differentcolor than liquid 42, blue liquid being employed as an example.

in operation of the embodiments of FIG. 4, when fluid system 10b is inits upright position a fluid jet 48 will be caused to be projectedthrough nozzle 32. At the same time, fluid system We will be reset,being it its inverted position, with the fluid 92 filling compartment220 and partially filling compartment 240. Thus, when fluid system 10bhas completed its operation and the device is inverted, fluid system 10cwill then operate to project a fluid jet through nozzle 320 to operatewaterwheel 90. At that time, fluid system 10b will be in its invertedposition and will be reset as previously described.

It is also possible to incorporate more than two closed fluid systemswithin a single device. This may be accomplished by providing concentricfluid systems in addition to the interleaved and inverted systems asshown in FIG..4. Thus, any number of fluid systems in either theinverted or upright orientations may be provided in a single device toprovide a highly stimulating and amusing apparatus.

A further variation is shown in the embodiment of FIG. 5. Here, again,the device is enclosed within a transparent plastic cylinder 12. Aclosed fluid system 10d includes a compartment 22 and a compartment 26corresponding to similarly numbered compartments in previously describedembodiments. In addition, an upper compartment 24d is divided into twochambers 94 and 96. An auxiliary compartment 64, corresponding tocompartment 64 in the embodiment of FIG. 3, is also provided betweencompartments 22 and 26. As previously described, compartment 64 issealed from the compartments of the closed fluid system 10d and containsa liquid 70 having a contrasting color (red in this example) to theliquid 46 (colored green) within closed fluid system 10d.

Fluid system 10d includes a tube 28d having an open lower end 3011within chamber 22 adjacent to wall 66 separating chamber 22 from chamber64. Tube 2811 extends upwardly through a wall 98 separating compartment22 from compartment 24d, through chamber 96 and through wall 100separating chamber 96 from chamber 94. Within chamber 94 tube 28d has anozzle end 32d at a position somewhat above wall 106. A curved siphontube 102 has an open end 104 closely adjacent to wall 100 within chamber94 and extends through wall 100 having an open end 106 thereat. Inaddition, a tube 108 has an open end lli) within chamber 96 closelyadjacent to wall 160 and extends upwardly through wall 100 and chamber94 to a point closely adjacent to wall 14, having an open end 112 atthis position.

Fluid system 10d also includes a tube 34d having an open end 36dcommunicating through wall 98 with chamber 96 and extending downwardlythrough compartment 22, compartment 64, and compartment 26 andterminating with an open end 38 near wall 16 within compartment 26. Thesystem further includes a tube 40d having an open end 42 withincompartment 22 closely adjacent to wall 98 and an open end 44 at wall68, separating compartments 26 and 64, communicating with compartment26.

The operation of the embodiment of FIG. 5 is similar to the operation ofthe embodiment of FIG. 3. However, the upper compartment has beendivided into two subchambers 94 and 96. After the fluid system 10d hasbeen inverted long enough to permit fluid 46 to fill compartment 22 andpartially fill chamber 94, the system is reinverted. At this time, fluid46 will communicate with open end 104 of siphon tube 102. The siphontube will then serve to siphon thefluid through open end 106 intochamber 96 and from chamber 96 through opening 36d and tube 34d intocompartment 26. This will cause air within compartment 26 to bedisplaced through tube 40d into compartment 22. The air pressurebuilding up within compartment 22 will force fluid from compartment 22upwardly through tube 28d and through nozzle end 32d thereof withinchamber 94. This will cause a fluid jet 48 to be created as previouslydescribed. As the fluid from fluid jet 48 is received within chamber 94,it will be siphoned by siphon tube 102 to chamber 96 where, aspreviously described, it will be communicated to lower compartment 26through tube 34d. It should be noted that tube 108 serves to maintainair pressure within chamber 94 for facilitating the operation of thesiphon tube 102. A stream of liquid 114 is shown flowing from siphontube 102 into chamber 96.

Any number of amusing devices may be created within the purview of thepresent invention. As already mentioned, various types of water toys maybe incorporated to operate in conjunction with the fluid jets providedwithin devices of the invention and various other devices may bestrategically located to be operated by the flow of liquid or air withinthe system. Highly artistic devices may be created by combining severalsystems of the invention and may, in certain cases, be useful for thecreation of artistic water sculptures and the like.

While the various embodiments of the invention have been described asbeing made entirely of transparent thermoplastic material, it is to beunderstood that other transparent materials may be employed, such asglass or the like. It is also not necessary that the walls of the devicebe made of entirely transparent materials. In some cases, some of thematerials or portions thereof may be opaque or translucent to add to themystery and appeal of the device.

While preferred embodiments of the invention have been shown anddescribed, it will be apparent to those skilled in the art that changescan be made without departing from the principles and spirit of theinvention, the scope of which is defined in the appended claims.Accordingly, the foregoing embodiments are to be considered illustrativerather than restrictive .of the invention, and those modifications whichcome within the meaning and range of equivalency of the claims are to beincluded therein.
